We have source server which is PI archive on the plant. Let's call it Plant PI. We also have a corporate PI server which gets data from Plant PI server. Plant PI and Corporate PI are in different domains. We use PITOPI interface to get data. There are small number of Corporate PI tags out of 10000 (about 10) have identical PI tag name/Instrument tag/description/pointtype as Plant PI. However, plant PI always have data and corporate PI tags stay as "PI Created" forever. We don't use Source Tag attribute and UserInt1 is always 0 for every tag. No compression and 0 exception for every tag in Corporate PI. What cause this and where do I start to troubleshoot?
